I have a 91 CRX SI with:

81.5mm LS/VTEC
CTR Pistons
PR3 Head
12.68:1 compression with Cometic .040" Headgasket
Crower Stage 3 Cams/Valvetrain
Ported ITR Intake manifold
I/H/E
Venom 310cc injectors
Venom 255lph fuel pump

I have a PR3 ECU and I'm looking for a basemap. (CROME?)
I know the injectors and fuel pump may be a bit on the big side, but i think they may work because I met a kid with close to the same setup(skunk2 stage 2 cams) doing 206whp, but hes got an OBD1 Teg.

 

check this sites.

Or if you want to use crome then you will have to convert to obd-1

 

Turbo Edit for OBD0---- I already have all BRAND NEW obd0 parts. I would be backtracking converting to OBD1

 

all you need for obd1 is to buy a converting harness and an obd1 ecu, then just pull out the pins on the distributor and re-wire it to obd1. (using a obd0 dizzy).

 

just use bre. great program, no bugs, worked well for my car.

 

never even heard of BRE. I talked to a tuner and he said Id be ok with OBD0 if I used turboEdit

BRE looks good, i know TE had many bugs a year ago and it seems development is dead. so i went obd0 and crome

 

Use BRE. go download it at pgmfi.org. That way you can use your pr3 instead of a ps9 or something. No reason to convert to obd1.

You betta rekonize! For obd0 vtec, BRE &gt;&gt; * Ben is the man, he's got a great app going, and a PR3 is the "right" way to do it. 4 maps &gt; 2. Plus all the other badass stuff it's got. Mmmmmm... Autotune.

Listen to this man!

 

Did you ever get the datalogging worked out?

 

Will I be able to start this thing without any tuning first? What should I do to get it running and not have a problem seating the rings?

 

u can start it, ubt what your afrs, maybe adjust the map with a correction factor of like 5% and dont beat on it. Get it running no problems, then goto the dyno and watch those afrs.

werd. Now if I can just get people to stop converting to obd1. Its not necessary most of the time!!

Never fear, I'll be putting a PR3 in my friends ls-vtec CRX, and BRE will handle my dirty work. Unless you've got a really ridiculous car and have some problem you need the special features of Crome to solve, OBD0 is the way to go.

 

Im just figuring with the CTR slugs and Big cams, tuning may be a bitch. But it seems like people are saying BRE is decent enough to tune the car.

 

No. It would be a bitch if you had some huge turbo and 1000cc injectors.

Ben

 

what about tuning ITB's later on?

 

I wrote ITB code (TPS only or map/TPS blending) but noone has tested it yet (to my knowledge). It comes with BRE.
